I need to remove Exchange 2003 files from our legay Ex2k3 box. The docs say at some point I'll need the installation disk. The 2k3 box has Exchange sp2 installed. I can't find an Exchange 2003 w/sp2 disk. Will the original 2k3 with no service pack work?Thanks

Yes, you can do the removal without a slipstreamed build. The original installer should be fine.
